<h4><a name = "tag_000_007_179">&nbsp;</a>NAME</h4><blockquote>
iswgraph - test for a visible wide-character code
</blockquote><h4><a name = "tag_000_007_180">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="wctype.h.html">wctype.h</a>&gt;

int iswgraph(wint_t <i>wc</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_007_181">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>iswgraph()</i>
function tests whether
<i>wc</i>
is a wide-character code representing
a character of class
<b>graph</b>
in the program's current locale, see
the <b>XBD</b> specification, <a href="../xbd/locale.html"><b>Locale</b>&nbsp;</a>.
<p>
In all cases
<i>wc</i>
is a
<b>wint_t</b>,
the value of which must be a
wide-character code corresponding to a valid character in
the current locale or must equal the value of the macro WEOF.
If the argument has any other value, the behaviour is undefined.
</blockquote><h4><a name = "tag_000_007_182">&nbsp;</a>RETURN VALUE</h4><blockquote>
The
<i>iswgraph()</i>
function returns non-zero if
<i>wc</i>
is a wide-character code with a visible representation;
otherwise it returns 0.
</blockquote><h4><a name = "tag_000_007_183">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
</blockquote><h4><a name = "tag_000_007_184">&nbsp;</a>EXAMPLES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_007_185">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
To ensure applications portability,
especially across natural languages,
only this function and those listed in the SEE ALSO section
should be used for classification of wide-character codes.
</blockquote><h4><a name = "tag_000_007_186">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>
None.
